Guaranteed delivery of changes to security policies in a distributed system

Abstract

Improved approaches for communicating changes to security policies (or rules) in a distributed security system are disclosed. Depending on the status of an affected user in the system, the changes can be delivered to the user if the user is logged in the system or effectuated in a state message in a local server and the state message is delivered to the user next time the user is logged in the system. If a local server is not operative at the time that a change request is received for a user of the local server, the change request is redirected to another local server. The user is directed to the another local server to affect the change request. As a result, various changes are guaranteed to be delivered to the affected users without compromising the network efficiency.

AI Technical Summary

Benefits of technology

[0127]The advantages of the invention are numerous. Different embodiments or implementations may yield one or more of the following advantages. One advantage of the invention is that policy changes are distributed only to those user computers (clients) that are affected by the policy changes. Another advantage of the invention is that policy changes are implemented timely, transparently and without user interaction. Still another advantage of the invention is that informing user computers about policy changes can be deferred until associated users are on-line (i.e., logged into security system).

Problems solved by technology

However, the advantages provided by the Internet come with a significantly greater element of risk to the confidentiality and integrity of information.

Without proper security means, an unauthorized person or machine may intercept any information traveling across the Internet and even get access to proprietary information stored in computers that interconnect to the Internet, but are otherwise generally inaccessible by the public.

However, it has been reported that many unauthorized accesses to proprietary information occur from the inside, as opposed to from the outside.

An example of someone gaining unauthorized access from the inside is when restricted or proprietary information is accessed by someone within an organization who is not supposed to do so.

Due to the open nature of the Internet, contractual information, customer data, executive communications, product specifications, and a host of other confidential and proprietary intellectual property remain available and vulnerable to improper access and usage by unauthorized users within or outside a supposedly protected perimeter.

Unfortunately, these various security means have been proven insufficient to reliably protect proprietary information residing on private networks.

For example, depending on passwords to access sensitive documents from within often causes security breaches when the password of a few characters long is leaked or detected.

These security systems, however, are not robust systems capable of efficiently and reliably permitting changes to security criteria, which is particularly challenging with security systems operating in networked environments.
